摘要
我们报告偏心温巨行星 TOI-201 b 的确认，它最初作为候选体在 \textit{TESS} 测光（Sectors 1-8、10-13 及 27-28）中被发现，并利用来自 NGTS 的地面测光以及来自 FEROS、HARPS、CORALIE 和 \textsc{Minerva}-Australis 的视向速度予以确认。TOI-201 b 围绕一颗年轻（）、明亮（V=9.07 mag）的 F 型恒星以 周期运行。该行星质量为 ，半径为 ，轨道偏心率为 ；鉴于宿主恒星的年轻，它似乎仍在经历相当快速的冷却。该恒星在视向速度和若干活动指标上也表现出长期变率，我们将其归因于恒星活动。诸如 TOI-201 b 这类温巨行星的发现与表征，对于约束巨行星的形成与演化理论十分重要。
